This invention relates to a protecting seal or casing adapted to be disposed about a coupling which connects a gas meter or the like with a supply pipe leading to the meter and an outlet pipe leading therefrom but it is to be understood that the seal or shield may be secured about a coupling at any point in a pipe line in order to protect the coupling and prevent it from being tampered with by unauthorized or careless persons.

One object of the invention is to provide a shield which may be disposed about a coupling and adjacent portionsof pipes connected thereby and not only prevent the coupling from being tampered with but also prevent danger of the coupling being accidentally struck and damaged. 7

Another object of the invention is to provide a coupling shield consisting of com panion sections of such construction that they may be easily applied to each other and secured in enclosing relation to the coupling. Another object of the invention is to so form the sections of the shield that, while they may be firmly held in engagement with each other and prevented from accidentally slipping out of place, they may be easily released and removed when necessary. v

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in elevation showing shields of the improved construction in place about couplings of a meter,

Fig. 2 is an enlarged side elevation of the 5 improved shield applied to a coupling.

Fig. 3 is a view showing one section of the shield removed and disclosing-the manner in which the shield fits about a coupling, and V Fig. 4 is a sectional view taken throughthe 4o shield on the line 4- of Fig. 2 with the coupling removed.

The meter, which is shown in Figure 1 and indicated in general by the numeral 1, is of a conventional construction and is provided. with the usual necks or pipes 2, extending therefrom so that the meter may be connected with a supply pipe 3 and service pipe 4. Each of the pipes 3 and 4t carries a nipple 5 which 7 is of curved formation, as shown in Figure 3,-

and this nipple is securely'but removably connected with one of the pipes or necks 2 of the!" It 'meter by a coupling 6. Persons have beenknown to disconnect a meter .and join the plpes 3 and i by a length of hose or pipe having its ends engaged with the couplings 6 and thereby Iuse gas without paying for the same and prevention of this is one of the principal. uses for which the shield or seal constitutingthe subj cot-matter of this invention is intended. I 6 .This seal or shield'consists of a hollow body or: casing, indicatedin general by the numeral.

7, and byreierring to Figures 3 and 4 it will be seen that the body or casing consists of a' pair of sections 8'and9 which are of a cup-like, 5 formationand of such size that when they are applied toeach other the casing or body formed thereby niayfit about the coupling and adjacent'po'rtions of the pipes 2 and 5,

as shownin'Figure 3. Companion recesses 10 are formed in the marginal portions of the sections 8 and 9 to receive the pipe or neck 2 and the opposite, side portions of the sec-1 tions are formed with extensions 11 which are semi-circular in cross section and cooperate to. form a neck which fits about'the nipple 5. It should ,be'noted that the neck formed by the extensions llis-disposed out of alinementwith the opening formed by the recesses 10 andis curved longitudinally in order to 210- 8'0 commodate the nipple, as shown in Figure 3.

. By this arrangement turning of the nipple in order'to loosen the coupling while the shield is still in place will be prevented. Flanges 1221116113 extend from the, margins of the sectionsbetween the recesses 10 and extensions ll'and provide the marginal portions of the; sectionswith wide faces which haveflat contacting engagement with each other, as shown in Figure 4. Tongues 11and-15 project from the flanges 12 ofthe section 9 atopposite "sidesof the section and the tonguel is cut' to form alongit'udinallyextending opening or slot 16, whereas the, tongue .15 is cut to-' formv a transversely extending slot. 17 and 51- bent adjacent the inner edge of thejslot to form an'oiiset free end portion 18. Compan-fl ion tongues 19 and20 extend from the mar-, ginal flanges 1-3 of the section 8, the tongue QObeing straight throughout its length-and ment by fastening means. 7 r

7 said body whereby the bodymay be" disposed the other, 1 being provided with outstanding tongues adapted to be engaged through the opening 17 in the tongue 15 and the tongue 19 being cut to form a strip which is pressed in order to form an eye 21 which fits through the open- 5 ing 16 in the tongue 14. Therefore, when the shield is applied, the tongue 20 may be engaged through the opening 17 and the two sections moved toward each other until they are disposed in enclosing relation to the coupling with their marginal flanges contacting and the eye 21 engaged'througn the opening I .16. A securing pin 22 may now be passed through the eye and a leaded-wire seal 23 threaded through an opening in the pin or apadlock may beeengaged through the eye. The shield will thus be firmly held in place and the couplings cannot be tampered with without detection.
